Embodiment
Combine accompanying drawing that the present invention is done further explain through embodiment below.
A kind of electromagnetic oven heating control circuit of the embodiment of the invention comprises coil driver and the control signal generation circuit that links to each other with above-mentioned coil driver, and above-mentioned control signal generation circuit comprises the memory cell that stores the Control Parameter change curve; Above-mentioned control signal generation circuit produces control signal and is input to above-mentioned coil driver according to the above-mentioned Control Parameter change curve that from said memory cells, reads, and controls above-mentioned coil driver to drive the corresponding thermal power of electromagnetic oven output.
Design of the present invention is: set corresponding electromagnetism mode of heating and heating curves thereof according to culinary art needs and experiment, the control electromagnetic oven heats dish according to this predefined heating curves (as shown in Figure 1, it is a kind of heating curves) automatically.
Said heating curves can be the needs according to different cooking methods (for example fry, burn, explode etc.) and different cuisines etc., and its culinary art heating process and heating characteristics obtain through simulating.
Said heating curves also can be to obtain through heating law and the heating process of simulating other type thermal source (for example naked light, steam, infrared etc.).
Electromagnetic oven generally is to heat through heater coil disc, to be used for realizing culinary art.Its basic operation principle is; Working power converts direct current into through rectifier; Become the high-frequency alternating current of 20～30kHz through the RF power conversion equipment from direct current again, this high-frequency alternating current is applied on the heater coil of heater coil disc, and its magnetic line of force penetrates the ceramic platen (crystallite plate) of electromagnetic oven and acts on the electromagnetic oven pan (being generally metal pan) of culinary art usefulness; The metal pan body is in this high-frequency alternating magnetic field effect; Because of electromagnetic induction produces eddy current, eddy current overcomes the internal resistance of metal pan body and accomplishes electric energy to heat energy conversion, the thermal source that the Joule heat that is produced is promptly cooked when flowing.
This shows that the thermal power of electromagnetic oven is relevant with the alternating magnetic field intensity in the heater coil, and alternating magnetic field intensity be applied to heater coil; Also be that high-frequency alternating current on the solenoid is relevant, we know that solenoid is a kind of inductive load; Its induction reactance is Z=SL, and wherein, L is the inductance value of solenoid; S=2 π f, f are the frequency that is applied to the high-frequency alternating current on the solenoid.So; I=U/Z can know according to the electric current and voltage formula; When applying voltage fixedly the time, as long as the high-frequency alternating current frequency on the control solenoid, the size of the high-frequency alternating current on can corresponding control solenoid; And then the alternating magnetic field in the control solenoid is strong and weak, thereby reaches the thermal power purpose of control electromagnetic oven.
Can know the working principle of induction cooker analysis by above, can control the thermal power of electromagnetic oven through the high-frequency alternating current frequency on the control solenoid.According to the heating curves of Fig. 1, it is as shown in Figure 2 to obtain corresponding high-frequency alternating current frequency variation curve, among Fig. 2; Abscissa express time, ordinate are represented the high-frequency alternating current frequency on the solenoid, similarly; This frequency variation curve roughly is divided into two stages, in the phase I; Frequency asks at any time and is index and reduce trend that when reaching certain hour (roughly at 15～20 seconds), frequency tends towards stability.
For this reason, the electromagnetic oven heating control circuit of the embodiment of the invention, through storage frequency variation curve shown in Figure 2 in memory cell, and according to this frequency variation curve generation control signal corresponding, the high-frequency alternating current frequency on the control solenoid.It should be noted that memory cell is not must this form of storing frequencies change curve, also can be other Control Parameter change curves, like the hereinafter example, and when at first producing voltage control signal, then can the storage voltage change curve in the memory cell.

As stated, in the second stage of frequency change, frequency is time to time change basically no longer, but tends towards stability.In order more accurately to control the frequency of high-frequency alternating current, can use Closed loop Control.As shown in Figure 4, the current signal through gathering solenoid produces control signal corresponding the drive signal that is input to coil driver is controlled as feedback, thus the alternating magnetic field intensity of control solenoid, with the thermal power of accurate control electromagnetic oven.
